This is neither about computers or music, but I'm hoping someone may guide me.

I recently received a new cable TV set top box to replace my outdated one. The old one had RCA audio output jacks which I connected to my home sound system via an RCA stereo lead, giving me excellent sound to watch TV & movies.


However the new cable box doesn't have RCA outputs, but it does have a USB3.0 which I understand is an outlet.

If I was to get a USB to RCA lead. do you think that would work? Or would it need some type of interface?

Thanks in advance.


Cheers,
Keith
